I DUST AND 'CHAFF COLLECTOR V 3 Application filed July 22,

, This invention relates to improvements in dust. and chaff collectors, andv more par- 'ticularlyi to dust and chaff collectors for grain eevator heads, and the objects of the invention are to provide a simpleand economically constructed device that can befitted to a grain elevator head whereby the chad, dust and the like, is efficiently and quickly separated from the grain. V

Further objects are .the provision of a dust and chaff cleaner for elevator heads are so arranged.

as to give more satisfactory and durablev service and which isnot liable in continuous operation to get out of order. 7

lVith t-heforegoing and other objects in view, 'the .invention consists essentially in the novel construction and arrangement of i of Figure. 2.

In the drawings,A designates an elevator head as a whole comprising a casing 10 transversely of which extends a shaft 11 provided with suitable bearings 12 and 13 on the supporting ribs 14 and 15 extending longitudinally on the outside of the casing. Fixedly mounted on this shaft within the casing is the elevator roller 16 on which is the'elevator belt 17. provided'with a plu adapted to be discharged.

ends-of the shaft are drive wheel ,19 chain connected to the source of power, and the drive pulley 2( respectively. The pulley20 is connected by a belt 21 to a smaller pulley 22 carried by a cross counter-shaft23 suitably supported. in bearings on a detachable stand 24 adapt ed. to engage and disengage through the recessed arms 25 and Y26 with the casing 10. On the other end of the driving pulley 27 connected by a belt 28 to 'a/puliey 29 hereinafter more fully keyed the sprocket described, thev foregoing construction being i more, particularly 3, 4 and 5. V

illustrated in Figures, 2, The inside ofhthe casing or head is 1 the protruding V the shaft 23is mounted provided with restricted and slanting partitions30 and 31 adjacent each side of the elevator roller 16, as shown in- Fig and is provided at the top withv a ablelid or cover 32.: Adjacent one side and extending partially and vertically upwards is a partitioning member 33 formingacom pa-rtment 34 with an opening in the bottom ure 5,

detach thereof35, and into this compartment the 7 grain carried by the elevator pockets 18, as illustrated in Figure 5, is, in operation,

lVithin this compartment 34 andsuitabiy arranged is a detachable baflie platelor spreader 36 con-- sisting of a pair of parallel spaced supportand 381(see Figure 11), bridged by a restricted cross member 39 so. that when placedin position as shown in Figure 5 the graindischarged in the ele-' vator'will contact first with the. bridge member 39 and then drop on each side the side of the elevator and partitionin the elevator, 33, respectively.

It will thus be seen that the grain dis-. charged from theelevatorwill in its travel. downwardlybeinterceptedv and spread and whileso spread-subject to the action of the blower, thus facilitating to a very great extent the cleaning of, it by'the more rapid a box casing member 4A to which is attached a housing for a fan. This casing extends parallel with the side of the elevator head and is provided at the-end opposite the fan housing with an extension 46 divided into two compartments a7 and 48 by a partition 49, the two compartments, it will be noted, opening into the single compartment 50 of the box casing which in turn communicates with the fan housing 45 in which is operatively mounted a fan 51.0n a shaft extending through the fan housing and through the casing and suitably journalled therein. This shaft 52 extends beyond the fan housing 45 to carry the pulley 29 beltconnected to the pulley 27, and whereby the fan, on the driving'mechanism being operated, is also operated. Above the extension 46 is adapted to fit a head or cover in the form of a casing 53 having a partition therein 54 registering with the partition 49, forming V the two compartments 55 and 56 corresponding to the compartments 47 and 4&8. The compartments 55 and 56 are connected through chutes 57 and :38 with openings 59 and 60 in the side of the elevator head whereby, on the fan being operated concurrently with the operation of the elevator and the discharge of the grain, as illustrated in'Figure 5, into the compartment 84L, a suction draft is provided for the grain while it is actually in the air and thus extracting from it all dust and dirt, throwing the same through the chutes 57 and 58 into the compartments 55 and 56 and thence into the compartments 4:? and A8 and from there into the grain box casing compartment to be finally discharged through the opening 61 (see Figures 7 and 8). To regulate the strength of this draft I provide a springheld door 162, as illustrated in Figure 10, and adapted to partially open or partially close the entrance of the compartment 49 to the main boxcompartment 50 to thus break the force or rush of the draught.

' 63 is a sliding door in the end of the elevator head.

From the foregoing it is believed that the operation and satisfactory results obtained from my improved dust and chaff eliminator or collector will be apparent. As already mentioned, when the fan or other drive from the source of power operates the sprocket Wheel 19 through the shaft 11, the pulley 20 and the roller 17, the elevator mechanism will be operated, and simultaneously withit through the belt and pulley mechanism the fan 51, thereby creating the necessary'dr'aft for automatically cleaning the grain in transit, the clean grain being discharged through the opening and the dust,'dirt andchaif being discharged through the openingfil.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention, within the scope of the claims, con structed without departing from the spirit or scope thereof, it is intended that all mat ter contained in the accompanying specification and drawings shall be interpreted as illustrative andnot in a limiting sense.

What I claim as my invention is:

1. A dust and chaff collector for grain'elevator heads comprising in combination with an elevator head, a casing adapted to detach ably engage with the elevator head, a fan in the casing, a main compartment'in the casing and compartments communicating with said main compartment, a detachable head for the casing and compartments formed in said head registering with the compartments in the casing, air chutes connecting the casing head with the elevator head whereby, on the fan being operated a suction air blast is created from the elevator head through said casing.

2. A device as claimed'in claim 1 in which a baffle plate is provided in the elevator head to temporarily check the grain in transit to subject it to'the suction air blast.

In Witness whereof I have hereunto set my hand.
